You use Pythagorean theorem to solve it and you get 18.3. Just look at the picture to see how i solved it
Answer:
5.24 feet
Step-by-step explanation:
First find the circumference of the circle. The formula is C=2πr. The radius is five so the circumference is approximately 31.42 feet. That means that in 6 seconds, the unicorn travels about 31.42 feet. To find the feet traveled in one second, you must divide 31.42 by 6 which equals approximately 5.24 feet.
Length = 6.25 feet
Your dad is designing a new garden for your
backyard. He has 20 feet of fencing to go
around the garden.
Let the width is X.
Length is 2 1/2 feet longer than the width i.e. (×+2 1/2) = (×+2.5) feet Perimeter = 20 feet
2(1+b) = 20
(I+b) = 10
(x+2.5+x) = 10
2x+2.5 = 10
2x = 7.5
x = 3.75 feet
Length = (x+2.5)
= (3.75+2.5)
= 6.25 feet
So, the length of the garden is 6.25 feet.
Answer:
x ≈ 11.7
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos26° = = ( multiply both sides by 13 )
13 × cos26° = x , then
x ≈ 11.7 ( to the nearest tenth )
There's 0.80 because 4/5 ×20/20 =80/100 And you can turn that into a decimal
